The Meaning Of Life: Summary & Key Insights

When Aristotle speaks of eudaimonia, he is not thinking of pleasure but of human flourishing — the realization of our potential in a community oriented toward the good. Thomas Aquinas later infuses this classical vision with Christian theology, suggesting that our ultimate fulfillment lies in God, yet still that moral virtue, reason, and love bind us socially. Both thinkers viewed meaning not as a private possession but as something realized through purpose and participation. For them, life’s purpose was not to feel satisfied but to act well, to harmonize one’s personal life with the shared enterprise of the good. These traditions locate value within an order beyond mere preference. Meaning, then, was bound to virtue and the communal fabric, not a matter of inner whim or existential improvisation.

The Enlightenment marks the decisive shift from this vision of a divinely or naturally ordered world to one where meaning becomes a human responsibility. With the decline of religious cosmologies and the rise of secular rationalism, the old harmony between heaven and earth collapses. Life is no longer narrated within a metaphysical story but within the human project itself. Where Aquinas could speak of telos in terms of divine grace, Enlightenment reason offers the autonomous subject as the new source of legitimacy. But autonomy, while liberating, isolates. Modernity emancipates us from the dictates of dogma but leaves us haunted by emptiness — the sense that to make meaning is our task alone, unsupported by any larger order. The question becomes psychological, even therapeutic, rather than ethical or communal. Thus begins the modern confusion between freedom and loneliness: to be self-legislating is exhilarating, but to be solely responsible for life’s meaning is also exhausting.
